3# If these # comments don't work, trim them. Don't worry about any other
4# shell scripts, Configure will trim # comments from them for you.
5#
6# (If you are trying to port this package to a machine without sh,
7# I would suggest you have a look at the prototypical config_h.SH file
8# and edit it to reflect your system. Some packages may include samples
9# of config.h for certain machines, so you might look for one of those.)
10#
11# Yes, you may rip this off to use in other distribution packages. This
12# script belongs to the public domain and cannot be copyrighted.
13#
14# (Note: this Configure script was generated automatically. Rather than
15# working with this copy of Configure, you may wish to get metaconfig.
16# The dist-3.0 package (which contains metaconfig) was posted in
dfe9444c
AD
17# comp.sources.misc and is available on CPAN under authors/id/RAM so
18# you may fetch it yourself from your nearest archive site.)

29SCO csh still thinks true is false. Write to SCO today and tell them that next
30year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31
32(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33we'd have to do is go in and swap the && and || tokens, wherever they are.)

2304df62 2120This installation shell script will examine your system and ask you questions
a0d0e21e 2121to determine how the perl5 package should be installed. If you get
2304df62
AD
2122stuck on a question, you may use a ! shell escape to start a subshell or
2123execute a command. Many of the questions will have default answers in square
2124brackets; typing carriage return will give you the default.
2125
2126On some of the questions which ask for file or directory names you are allowed
2127to use the ~name construct to specify the login directory belonging to "name",
2128even if you don't have a shell which knows about that. Questions where this is
2129allowed will be marked "(~name ok)".

2134 . ./myread
2135 cat <<'EOH'
2136
2137The prompter used in this script allows you to use shell variables and
2138backticks in your answers. You may use $1, $2, etc... to refer to the words
2139in the default answer, as if the default line was a set of arguments given to a
2140script shell. This means you may also use $* to repeat the whole default line,
2141so you do not have to re-type everything to add something to the default.
2142
2143Everytime there is a substitution, you will have to confirm. If there is an
2144error (e.g. an unmatched backtick), the default answer will remain unchanged
2145and you will be prompted again.
2146
2147If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2148the questions and use the computed defaults (or the previous answers if there
2149was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 2150You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 2151on the non-interactive behaviour for the remainder of the execution.

2157Much effort has been expended to ensure that this shell script will run on any
2158Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
2159Configure and run it again. If you can't run Configure for some reason,
2160you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 2161have, let me (perlbug@perl.org) know how I blew it.

2163This installation script affects things in two ways:
2164
21651) it may do direct variable substitutions on some of the files included
2166 in this kit.
21672) it builds a config.h file for inclusion in C programs. You may edit
2168 any of these files as the need arises after running this script.
2169
2170If you make a mistake on a question, there is no easy way to back up to it
2171currently. The easiest thing to do is to edit config.sh and rerun all the SH
2172files. Configure will offer to let you do this before it runs the SH files.

3528stdio mechanism is still available if needed. The abstraction layer
3529can use AT&T's sfio (if you already have sfio installed) or regular stdio.
3530Using PerlIO with sfio may cause problems with some extension modules.

3604Since release 5.6, Perl has had two different threading implementations,
3605the newer interpreter-based version (ithreads) with one interpreter per
3606thread, and the older 5.005 version (5005threads).
3607The 5005threads version is effectively unmaintained and will probably be
3608removed in Perl 5.10, so there should be no need to build a Perl using it
3609unless needed for backwards compatibility with some existing 5.005threads
3610code.
